关于HttpWebResponse线程阻塞的问题
程序运行 偶尔会在运行到myRes = (HttpWebResponse)myReq.GetResponse();
这句的时候出现异常进入catch：System.Net.WebException:请求被中止:操作超时此时 这个线程就阻塞了，主线程没反应了。。。
finally里明明已经全部释放了
代码在下方 大牛来吧 ！！！！万分感谢
private bool SendReport(string dttm,string strnewid,string strcontent)//string NewReport { bool a = false; string strresponseid = string.Empty; string strdateandid = string.Format("{0:yyyyMMddHHmmss}",dttm)+strnewid; strcontent = strcontent.Replace(" ","<bl>");//替换空格 strcontent = strcontent.Replace("\r\n","<en>");//替换换行 ASCIIEncoding encoding = new ASCIIEncoding(); string postData = "report="+strdateandid+":"+strcontent; byte[] str = encoding.GetBytes(postData);//编码字符串 HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(frmIP.PostIP); myReq.Method = "POST";//设置请求的方法 myReq.ServicePoint.ConnectionLimit = 20; myReq.ContentType = "application/x-www-form-urlencoded";//一个疑问 myReq.ContentLength = str.Length;//获取字符长度 myReq.ServicePoint.Expect100Continue = false; HttpWebResponse myRes=null; try { using (Stream sm = myReq.GetRequestStream()) { sm.Write(str, 0, str.Length);//向公网写数据 } myRes = (HttpWebResponse)myReq.GetResponse(); if (strcontent != "CH") { using (StreamReader sr = new StreamReader(myRes.GetResponseStream())) { strresponseid = sr.ReadToEnd(); //strresponseid = string.Empty; if (strresponseid == "") { ChangeSendSignData(strnewid, dttm, 0); } else ChangeSendSignData(strnewid, dttm, 1); } } a = true; } catch(Exception ex) { ChangeSendSignData(strnewid, dttm, 0); txtThrowRong.AppendText(DateTime.Now.ToString() + " POST数据异常，请确认网络连接良好 流水号:"+strnewid+"\r\n"); txtThrowRong.ScrollToCaret(); string strErrors = DateTime.Now.ToString() +" POST数据异常\r\n" + "错误报告:" + ex.ToString() + "\r\n\r\n"; File.AppendAllText("Errors.LOG", strErrors); SendErrorsLog(strErrors); a = false; } finally { if (myReq != null) { myReq.Abort(); }//销毁HttpWebRequest 必须 if (myRes != null) { myRes.Close(); myRes = null; } } return a; }
